A decrease in the speed of rotation of a spinning object, in particular a celestial object or computer disc.
（尤指天体或计算机磁盘的）自旋减慢
Example sentencesExamples
However, the relationship between spin-down rate and magneto-dipole losses is not as straightforward for pulsars that also emit X-rays.
Recent measurements show that the actual characteristic spin-down period of the GP-B gyros exceeds 10,000 years-well beyond the requirement.
The monomeric KpnI fragments, separated from plasmid vectors and gel purified by the spin-down method, were labeled with flourescein - 11-dUTP (Amersham Pharmacia Biotech).
